<p>
        Note that these tests are carefully designed to test performance of the underlying
        algorithms and not memory allocation or variable copying. As usual, performance
        results should be taken with a healthy dose of scepticism, and real-world
        performance may vary widely depending upon the specifics of the program.
        In each table relative times are given first, with the best performer given
        a score of 1. Total actual times are given in brackets, measured in seconds
        for 500000 operations.
